. To all 'whom t may concem.:

Be it known that we, THOMAS IV. Bm and MARTIN L. Brun, citizens of theVUnited States, residing at Montesano and Olympia, respectively, in thecounties of Grays Harbor and Thurston, respectively, and State ofYashingtoin have invented certain 'new and useful Improvements inCream-Separators; and we do hereby declare the following to be a'full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to cream separators and while particularlyadapted to siphoning of cream from bottles is not limited thereto.

An object of this invention is to provide a cream separator in which theflow of cream is started by gravity to act upwardly acting directly uponthe cream.

In previous siphoning devices for separating cream one of tl eimpractical features of the device has been the means of starting theflow of the cream, for which various expedients have been used, such asair pressure and the like, which has made such a cumbersome andexpensive and complicated device as to render it of little value ,forusual household use. An object of this invention is to simplify thestructure of a crealn separator of this character and to provide astructure in which the tube crosses the cream diagonally and in whichthe tube leaves the bottle at the side of the cap in order to provide ameans whereby the siphoning may be started by merely tipping the bottle,whereas in former devices if the bottle were tipped it would have to betipped so far that the cream would be disturbed.

lith these and other objects in view the invention consists in theconstruction, the combinationl the detail, and arrangement of parts ashereinafter more fully described and claimed. v

In the drawings:

Figure 1 is a longitudinal section medial through an ordinary milkbottleprovided with the invention herein.-

Fig. 2 is a plan View of our device. Fig. 3 is a view of Fig. l in whichthe bottle has been tipped.

Fig. 4 is a section at 4-4 of Fig. 3.

Fig. 5 is a modified form of the lower tube shown in Figs. l and 3.

Figs. 6, 7 and 8 are plan views of the three disks forming the bottlecap.

In the embodiment of this invention there is provided a Siphon tube 2terminating in a J tube in the interior of the bottle 3 and passingthrough and alixed to a stopper et, the said siphon tube entering at oneside of said stopper and passing at an angle .therethrough so that themouth of the said J tube is in juxtaposition to the opposed side of saidbottle from which the said tube enters. The said stopper is made up ofthe following parts: A handle A, a metallic top disk B, a compressibledisk C and a metallic lower disk D, the said mem@ bers being heldtogether by a screw E. The J tube is expanded at its upper end andcarries a packing gland F, which gland is held in place by lugs Gr.

As shown in Fig. l, the milk bottle is standing vertically and thedividing line be is tipped to the position shown in Fig. 3,

the mouth of the J tube will still be in the cream and gravity willstart the flow of the cream and the Siphon effect is started. It istherefore quite obvious that owing to the angular-ity at which theSiphon tube passes through the bottle and its positioning in the bottlethat the cream will start to flow when the bottle is so tipped withoutthe milk fiowing therewith, and also that this siphoning maybe startedwithout such commonly used methods of starting Siphoning, asa pressuresystem, and that all that is necessary in the applyingof this device toa milk bottle is to insert the stopper in the milk bottle and tip themilk bottle to start the siphoning. It will be noted further that theend of pipe 2 is always within the cream, and that when the suctionceases, the iow automatically ceases, .and since the mouth of the J tubeis always at substantially the dividing line between the milk and toitself and allow the cream to automatically run out slowly in itscourse.

What we claim is:

In a siphoning device the combination of a tiltable container having amouth, a closure for the mouth having a Vent hole, and a Siphon tubehaving its short leg passing -through and secured to the closureadjacent one side atan angle so that its open end 10 will be locatedadjacent the Wall of the conf tainer on the opposite side whereby thetilt- Ing of the container will cause a reliminary grav1ty flow of itscontents t rough the Siphon without spilling or agitating the contents.

In testimony whereof we affix our signatures.
